Preservation for electronic discovery has become a complicated, multi-faceted, steadily changing concept in recent years. Starting with the nebulous determination of when the duty to preserve arises, then continuing into the litigation hold process (often equated to the herding of cats) and the staggering volumes of material which may need to be preserved in multiple global locations, platforms and formats, the task of preservation is an enormous challenge for the modern litigator. Seeking a foundation in reasonableness, wrestling with the scope of preservation is often an exercise in finding an acceptable balance between offsetting the risks of spoliation and sanctions related to destruction of evidence, against allowing the business client to continue to operate its business in a somewhat normal fashion.
